Lowest Cost Re-Roofing
95% of the Time
Highest performance all the time
Imagine a roofing system that provides more than 20 years of leak-free performance with little-to-no maintenance. Imagine that same roof giving you improved building energy efficiency, the industry’s best severe weather resistance and the lowest lifecycle cost.
Now imagine installing it directly over your existing roof and saving labor, hassle, disposal costs and the environment all at once.
Low lifecycle cost,
Low-maintenance, leak-free,
and Energy efficient
Studies conducted by Structural Research Inc. for the National Roofing Foundation, Texas A & M University, Michelsen Technologies, LLC and the National Roofing Contractors Association show that SPF roofing systems:
- Offer the lowest lifecycle cost
- Provide 20 to 30 years of low-maintenance, leak-free performance
- Install directly to existing substrate in almost all retrofit situations, reducing costs and landfill waste
- Improve building energy efficiency through superior insulation properties and elimination of thermal bridging
- Provide the highest wind uplift and severe hail resistance in the industry
- Are sustainable through recoating
ELASTOSPRAY® spray-applied polyurethane foam roofing systems, ELASTOCOAT© protective coatings and AmeriGlue© polyurethane insulating adhesive have been tested and approved by third-party accreditation to meet and exceed most performance requirements.
Insulation is not Enough
Improve energy efficiency by 40%
Building scientists agree that you need an air barrier to make a building truly energy efficient. That's because up to 40 percent of conditioned air escapes through the cracks, gaps and holes that exist in the envelope of the average American building.
When air leaves the building, it takes moisture and pollutants along for the ride, contributing to premature deterioration, mold and mildew.
Reduce air leakage by up to 83 percent
A study from the National Institute of Standards and Technology (NIST) shows continuous air barrier systems reduce air leakage by up to 83 percent, for potential gas savings of greater than 40 percent and electrical savings greater than 25 percent.
Massachusetts, Wisconsin and Michigan mandate air barrier systems under their Commercial Energy Codes. The American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) will mandate air barriers under Addendum z to Standard 90.1-2004.
To meet these standards, an air barrier system must:
- Have an air permeance rating less than 0.004 cfm/ft2
- Be continuous throughout the building envelope
- Have interconnected, flexible joints
- Be able to withstand positive and negative wind pressures without displacement
- Be durable enough to last the life of the building
The
WALLTITE® Insulating Air Barrier System is approved by the Air Barrier Association of America (ABAA) to meet and exceed these Code requirements.
